IMPROVEMENT IN SASH-BALANCES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom. z't'may concern:

Be it known that I, CASPER VAN Hoosnn, of Catskill, in the county of Greene and in the .State of New York, have invented certain new and useful Improvements in Sash and Weight Attachment and Lock; anddo hereby declare that the following is'a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The'nature of my invention consists in combining perforated metallic strips arranged with the sash and weight, and operated by toothed wheels-placed inframes between the sash and window-frame, the said weights running in guides and being provided with friction-rollers; also, in the construction of thelocking device for holding the sash, as will be more fully hereinafter set forth.

In order to enable" others skilled in the art towhich my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- .jFigure 1 is a front or face view of aside of a window-frame representing my sash-balance and lock in position, the.sash, parting-strip, and front-stop being removed.

Figure 2 is a side cross-section view of the entire arrangement.

d A represents the position of the front-stop of a winow. v

B B, the pulley-stile or side of window-frame, against which the side of the sash or sash-stile slides.

O G are shallow grooves about one-quarter inch deep and five-eigthths wide, out the entire length of the pulley-stile B, and in a line withthe center of the pulleys or wheels.

D is the deep groove in the pulley-stile for partingstrip, which may be dispensed with in this arrangement if so desired.

E is the back or outer stop.

. F is a thin backing-piece to the weight-case.

G is thesash-stile.

H is the weight, having secured to its upper end a friction-roller, I, as seen in fig. 2, which rolls against or in a shallow channel cut in the surface of said backing-piece F, and so'guiding the upper end of the said weight.

J'J are the pulleys or wheel-frames, which are let in the pulley-stile or side of the window-frame even with its time-surface, and in center line with the grooves G 0, being in line with the sash-way.

Two of said pulleys or wheel-frames are shown in fig. 1, being one for each sash, and joined together in one by a connecting-bar which has a hole in its center, through which is passed awood screw, a, cntering'in the solid wood of the. window-frame at the bottom of the parting-strip grooveD, thus holding said wheelin them to correspond withand work on the pin-cogs of the wheels K K.

' These perforated metallic strips are confined and pass freely up and downbetween the body of said wheel and the inner surface of the wheel-frames front and .backslotted plates.

There are two strips used in connection with each wheel, one oneach side. The one on the outside, which slides in shallow grooves C in the pulley-stile B, and between it and the sash-stile G, has its ends bent over and screwed to the top and bottom of the sash, as shown. The other or inner metallic perforated strip has its lower end bent under and hooked on the hooking-pin l), at the-lower end of the weight H. The upper end of this strip maybe free or guided by a wire or other suitable means.

M is a knob attached to one end of a wire rod, the

other end of which is attached to one side of an evener or lever, N, which turns on'the shank of the screw 0,. I This lever N is placed behind the bar which connects the two wheel-frames J J, and within the parting-strip groove D, in which it freely plays hnder said slots in front of the perforated strips L L, and between the pin-teeth of the wheels K K, prevent the turning of said wheels andthe consequent movement of the said strips, sash, and weights, thus completely and securely locking the'windows. I P is a slight spring placed 'in the parting-strip groove, to act on the lever N to force the bolts 0 O inward and insure the locking. effected by pulling the knob M.

Having thus fully described my invention, I \Vhat I claim asnew,"and desire to secure by Letters Patent, is
